Question 7
#7) What value of m makes the equation true?
3(8 – m) = 5m – 40

Answers

Answer:

Step-by-step explanation:

3(8-m)=5m-40

you first distribute 3 through the parenthesis

24-3m=5m-40

Move the variable to the left and change sign

24-3m-5m=-40

now move the constant to the right

-3m-5m=-40-24

collect like terms

-8m=-40-24

-8m=-64

Divide both sides by -8 and negative divide negative number becomes positive

so m = 8

so I put your equation in cymath. feel free to use it whenever you need help. it really do comes in handy.

Liam suggests adding some other cards to Sia's game Part A Liam explains that drawing a yellow card is equivalent to drawing a blue card followed by a red card. How many spaces forward or backward does a player move after drawing a yellow card? Justify your answer.

Answer:

2 squares backward

Step-by-step explanation:

Given the rule :

Blue card = 4 squares forward

Red card = 6 squares backward

Yellow card = drawing a blue followed by a red

Spaces moved after drawing a yellow card:

Yellow equals :

Blue = + 4 squares ; then

Red = - 6 squares

Net total movement :

Blue + red

Step-by-step explanation:

Kevin is a server at an all-you-wish-to eat sushi restaurant. At one table, the customers ordered 3 child meals and 2 adult meals, which cost $80 in total. At another table, the customers ordered 5 child meals and 3 adult meals, which cost $125 in total. How much does each child meal and adult meal cost?

Answers

Answer:

Read below for full answer :)

Step-by-step explanation:

We can conclude that the total cost of all meals was $205.

There were a total of 8 kids meals and 5 adult meals.

You'd have to divide 205 by 8, and you'd get 25.625.

Then, divide 205 by 5, and you'd get 41.

For example, we could say that each childrens meal was $15 ($120 total in kid's meals), and each adult was $17 ($85 total in adult meals).

When you total $85 and $120, it then given you a sum of $205.

There are many ways to complete this equation, but i feel that this is the easiest way.

Hope this helps! :)

180 feet / day is how many centimeters (cm) /hour?

Answers

Answer:

1.27cm/hour

Step-by-step explanation:

there are 24 hours in a day, and 30.48 centimeters in a foot.

180 / 24

7.5

so that is 7.5feet / hour

convert the feet into centimeters

228.6 cm/hour

Unit conversion is a way of converting some common units into another without changing their real value. 180 feet per day in centimeter per hour will be equal to 228.6.

What is Unit conversion?

Unit conversion is a way of converting some common units into another without changing their real value.

for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given the rate as 180 feet per day. This can be written in cm/hour as,

180 feet per day

= 180 feet / 1 day

Since 1 feet equal to 30.48 centimeters, also, 1 day has 24 hours, therefore,

= (180 × 30.48) centimeters / (1 × 24) hours

= 228.6 centimeters/ hour

= 228.6 centimeters per hour

Hence, 180 feet per day in centimeter per hour will be equal to 228.6.
